Specification of Letters Patent. Application filed August 11.1906. Serial No. 330.181.

Patented Dec. 3,1907;

To all whom it may concern:

Be it known that I, WARREN W. ANNA- BLE, a citizen of the United States, residin at Grand Rapids, 'in the county of Kent an State of Michigan, have invented certain new and useful Improvements in Track-Grind ers and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. b

My invention relates to track rinders, "and more particularly to such grin ers ada ted to reducing ine ualities at the joints 0 the rails of car track, after the rails are in position,- and its object is to provide a device which will rapidly and effectually perform this work; that may be handled by one operator, that is provided with means for self propulsion from place to place as occasion or 1ts use may require.

My device consists essentially of a truck upon which is mounted a motor to provide power for propulsion, and to drive the grinders, a clutch between the motor and the 'proelling gearing, a counter shaft, grinder eads driven from the counter shaft, a reversible feed mechanism adapted to traverse the machine to and fro l o n itudinally of the rails, means to traverse t e grinder heads to and fro transversely of the rails, means for raising, and lowering the grinder heads,

means for contacting the grinding wheels with the rails and adjusting said wheels laterally of the rails, and in the combination bein ha to the accompanying drawings, in

Figure 1. is a sideelevation with parts removed; Fig. 2 a plan view of the same with other arts removed; Fi 3. a transverse vertical section, looking orward, taken on the line 33 of Fig. 1.; and, Fig. 4. adetail of the feed mechanism shown in front elevatlon.

Like numbers refer to the figures.

1 represents a truck frame mounted on axles 2 and 3. Upon this frame is mounted like parts in allof a second frame 4 with elevated portions 5 to carry the trolley ole (not shown) to conduct the current to t e controller 20 and to the motor 6. I,

Fixed on the armature shaft 7 is a pulley RAPIDS, MICHIGAN, Assrenon To 0. VALLETTE KASSQN, 7 or CHICAGO, ILLINOIS.' I I 13','which through a belt 16 and pulley 15 on the counter shaft 14 serves to drive said counter shaft when the belt tightener' 17 is down. This countershaft 14 is mountedin elongated journal bearings 46, upon the out-- side of which journal bearings and adapted to slide longitudinally thereon, are mounted double yoke arms 22, on the vertically swinging ends of which are journaled arbors 23 carrying abrasivewheels 24, and having pul-.'

leys 52 to which motion is imparted by belts abrasive Wheels 24, there are provided screws 27 jlournaled in the frame 4, and provided wit hand wheels 28 at their upper ends.

traversing the abrasive wheels transversely These'screws engage a nut 25*,havmg 'oppo'se arms 22. To take up any lost motion in this adjusting means, a contractile spring 29 is attachedto the frame 4 at itsupper ingi extensions 25 slidable in cars 26 on the yo end and connected to the arms 22 at their lower ends.

The means for movin the machine from .-placeto place consists 0. a shaft 8 journaled in bearings on the frame work 4 and in line with the armature shaft 7. On the inner end of thisshaft 8 is one member of amagnet'ic 'clutchQ, the other member of which is the web of the-pulley-1'3, which pulley is fast on the armature shaft 7. On this shaft 8 is a pinion 8, which meshes with an idler gear 10', journaled on' the stationary shaft 10*.

- Journaled on a stud 11 is another idler grinding, the machine is traversed to and fro by means of a car 30 fixed on the axle 3, and n mesh Wit the pinion 31 fixed on the shaft 56, which shaft is journaled in a 1 frame 55.- On the shaft 56 1s also fixed a worm gear 32, which is engaged by a worm 33 fixed on the shaft 36, which shaft is mounted in a pivoted frame 37.

Slidable on the shaft 36 is a splined hub 36*, on which are fixed bevel gears 34 and 35 adapted to-alternately mesh with a bevel pinion 54 fixed on the inner end of a shaft 116 51. On the opppsite end of'this'shaft is a pulley 49 to w 'ch-motion is transmitted from a pulley 53 on the countershaf-t 14 by .means of a belt 50. This shaft 51 is jour-.

naled at the outer end on the frame 4 and at theinner end on the frame 55. To cause the bevel gears 34 and 35 to alternately mesh with 'the bevel pinion 54, a pivoted lever 44 is provided having a yoke at its inner end, which engages agroove in the splined hub 36, to shift the same long'i-' tudinally on the shaft 36 and thus reverse the motion of rotation of the same. a

frame. rod 39 at the When-moving the machine fromrplace .to place it is necessary to disengage the worm from the worm gear. For this purpose the frame 37 is pivoted at the rear on the frame rod 38 and detachabl supported on the out. To raise and lower the front of the frame, a lever 41 is pivoted on a standard 42 and connected by.

a link 40 to the front of the frame.

When the worm 33 and worm gear 32 are in mesh, the forward end of the frame 37 rests on the rod 39, the lever 41 engages a. notch 43? in'a catch 43 andthus the gears I are locked in mesh. When it is desired to disengage the worm and worm gear, the lever 41 is depressed and caused to engage the notch 43 in the catch 43. This raises the front end of the frame 37 off from the clutch 9 isthrown in.

rod 39, andhigh enough. so that the worm 33 is clear of the worm gear 32. 1

The operation of m device is as follows:

When moving from p ace to place thetbelt tightener 17 lsraised so that the belt 16 is loose. The abrasive -wheels 24 are raised to clear obstructions, the worm 33 is thrown out of mesh with the worm e.ar'32, the electric switch that operates t e magnetic In this condition the machine is run over the road and operated from the controller 20 withthesame facility as an motor car.- Whenthe machine has arrlved at its "place to work, the switch that operates the magnetic clutch is opened, the belt tightener is put on the belt 16, the worm and worm gear are put in mesh, the abrasive wheels lowered to opera-- tive position and the device is ready for grinding 5 the rails, lateral adjustment by meansof the levers being used for curves or to shift the contact of the rim of the wheels, as occasion requires. Thus I. provide a machine which is rapid, efficient, and is handled entirely; by one operator.
